Zi) aZZ whom it may concern:

Be 'it known that I, FRANZ A. FULLER, a

citizen of the United States, residing in the city of Newark, in the county of Essex and State of ,Xew Jersey, have invented certain new' and useful Improvements in Safety- Razors of which the following is a full, clear, and exact description, such as will enable'oth'ers skilled in th art to which it p rtains to make, construct, and use the same, reference being had to the accompanying drawi1'1gs,,aiul to numerals of reference marked thereon, forming a part of this specification.

The object of my invention is the production of a safety razor which shall be simple in construction, compaatively inexpensive in cost, and provided with means for seeurely holding a detachable blade in position, and also provided with means for securing a detachable razor blade sharpening device thereto forth .and pointed outin the claims. lVhile With this end inview, my invention consists 1n certain novelt es of construction and arrangements of parts, as hereinafter set tl1e,1 ljifel,letl formsrof my invention are illustratedin the accompanying drawmgs,

yet is to be understood that minor detail changes may be made without departing from the'scop'e thereof.

In the accompanying drawings,

Figi'irel represents a side elevation of my in'iproved safety razor, with a removable razor blade sharpening device secured there- -to. showing the cutting edge of the razor blade; in engagement with the roller of the sharpening device.

Fig. representsgon an enlarged scale, a

fragmcntaryside elevation of my improv d safety razor.

rites represents a similar view, showing the blade holder in a vertical position.

Fig. 4c represents a sectional side elevation taken on linens-a3 of Fig. 5;and

'i'epresents a fragmentary front elevation. showing the blade holder in a vertical position. I

Similarnumerals of reference refer to like parts throughoutthe specification and drawto provide resilient clamping jaws to receive the razor blade between themselves, and fur the! bent to receive a pintle 3, the ends of which are enlarged or riveted over as at 4:, and by means of which the blade holder is slidably and pivotally connected to the frame 5. This blade holder is also provided with two pressed-out portions 23 on one of the clamping jaws of the blade holder, to engage with two apertures inthe blade 1 to firmly secure and prevent the accidental displacement of the blad 1 from said holder 2.

The frame 5 is preferably made of sheet metal, stamped and formed from a single q blank, and so constructed as to grip the blade 1 at the front corners, the sharpened edge of the blade resting upon the bent-over guard 6, which is provided with the usual perforations 7, the free end of which is bent far beyond the guard 6, to at all times mainQ tam the cutting edge of the razor blade in the proper and adjusted position relative to the guard teeth. These stops 8 may, for convenience sake be formed integral with the frame 5.

9 represent upwardly extending side pieces formed integral with the frame 5, each side piece being provided with an elongated slot 10, toreceive the'end of the pintle 3-; by means of which the blade holder 2 is slidably and pivotally mounted in the frame 5. A handle 11, provided with two outwardly extending curved arms 12. is secured to the underside of the frame 5 by means of rivets 13.

Near the frontedge' of the frame 5, ad-[ jacent to the uard 6', and extending preferably across t e entire frame, I provide. a. pressed-out portion 24:, designed as a guide.

which. together with the ends 25 of the blade holder 2, which also serve as guides, provide convenient means assistmg the cut-' ting edge of the blade to engage with the stops 8, the ends 25 being designed to have sliding engagement with the upwardly extending side pieces 9 of the frame 5. These ends 25 also serve as convenient stops, which engage with the rear edgeof the frame 5,

The forward and outer end of the guard to limit the rearward movement of the blade holder 2.

An elongated slot 1% is centrally arranged in the frame 5. to receive the rectangularlug 15, which is preferably formed integrally on the under side of the blade holder 2, and by means of which, together with the locking bar 16, the blade is locked p in its adjusted position.

' The loclzing bar IQ is slidably mounted in a housing 17, which is secured to the under side of the frame 5 by means of iii- .20, to the same depth as the rear of the slot 14, to receive the rectangular lug 15. formed on the blade holder 2. The locking bar'is preferably a piece of fiat sheet -'metal ,vstamped and formed from a single blank, and provided with down-turned ends or push members 28, whereby the locking bar can be moved in either direction.

19'represehts a recess or cut-away por- .fiOIl, extending inwardly from the front edge of the locking bar, so that when the locking bar is moved as far as possible in one direction, the recess or cut-away portion 19 thereof, will register with the slot 14. and permit the lug 15 of the blade holder 2 to pass through the slot 14 of the frame and through the recess 19. as well as through the cut-away portion 20 in the housing 17 in order that the locking bar .might be moved as far as possible in the opposite direction, thereby causing the edge of the locking bar, adjacent the recess 19. to engage with the lug 15, to lock the blade holder with its attached blade, in its adjested position.

An elongated slot 21 and an integral loop 22arranged adjacent to said slot, is formed near the rear edge of the frame 5, to provide means for securing a razor blade sharpening device, forming the subject matter of a co-pending application, and by means of said .device, the cutting edge of the blade,

lying. adjacent to the guard maybe sharpened without removing the blade from the frame.

To operate my razor, the blade holder 2,

with a razor blade therein, is moved from the position illustrated in Fig. 2 of the drawings, into the position illustrated in Figs. 3, 4 and 5, by moving the locking bar 16 in the direction of the arrow as indicated in Fig. 5, into the position shown in dotted lines in said figure, thereby causing the rectangular lug 15 of the blade holder. The blade holder 2, with its attached blade, is then moved over the' guide 24 and side pieces 9, thereby disengaging the cutting edge of the blade from the stops 8. After the blade holder has been moved into the position shown in dotted lines in Fig. 3, it is then 1 swung into the vertical position shown in said figure, in order to cleanse the blade 0},711 to remove the same from the holder, or to'- attach the sharpening device 26, said sharpening device being provided on its under side with a lug corresponding to the lug 15, whereby the said device is locked to the. frame 5 in substantially the same manner as the blade holder 2. v

The present invention provides a very efficient and exceedingly simple safetv razor, the same being constructed of a minimum number of parts. and reduced to the simplest operative etiiciency, said parts being of such shape as to lend themselves readily to manufacture by the use of suitable punches and dies from ordinary sheet metal.

I am aware that changes may be made in the several arrangements of the various parts, as well as in the details of construction thereof. without departing from the scope of my present invention; hence I do not wish to be limited to the arrangements and combinations of parts as herein shown and described, as obvious modifications will suggest themselves to those skilled in the art.
